SPECIFICATION d I Application filed June 27, 1902.
To all whom t may concern: l
Be it known that I, MA'rILDA L. TRAPP, a citizen of the United States, residing at Los Angeles, in the county of Los 4Angeles and.
State of California, have invented new and use-y ful Improvements' in Smelt'ing-Furnaces, of which the following is a specification.
- My invention relates to and has for its object to provide an improved apparatus for smelting ores and other material with liquid ,y fuel capable of smelting large quantities of ore by reason of its being adapted for continuous operation. I accomplish this object by means of the furnace herein describedand shown in the accompanying drawings, in which- Figure l is a central vertical section of a furnace embodying my invention. Fig. 2 is a central vertical section of a like furnace, taken at right angles to the section taken in Fig. 1. Fig. 3 is a horizontal section of a similar fur.- nace, taken on line 3 3 of Fig. 2. Fig. 4 is a horizontal section of a similar furnace, taken on line 4 4 of Fig. 1. Fig. 5 is a perspective view of the grate-bars and one end and one side' wall shown, the other end and side wall being removed.
My improved furnace consists in an outletstack A or cupola, which I have shown square in horizontal or cross section, across the lower part of which I place a grate B, which divides the stack into two chambers, an upper and lowerv one. The spaceimmediately above the grate I term the smelting-chamber and designate it inthe drawings by the letter C. This grate is composed of a series of gratebars B', preferably made of graphite or ganister clay. The grate-bars are inclined upward from the two opposite side walls, into which their lower ends have a footing, to their junction in the center, where their upper ends abut, for the purpose of imparting strength thereto to lwithstand the weight of the ore to be placed thereon, which is introduced through the ore-charging opening H. The grate-bars are properly spaced apart to permit the passage therebetween of the products of the ore after it arrives at a molten condition to the smelting-chamber. The chamber-space immediately beneath the grate I forming part of Letters Patent No. 749,954, dated January 19, 1904.
Serial No. 113,533. (No model.)
term the receiving-chamber D and is shaped much like an oval basin and receives the molten metal as it runs from the smelting-chamber above. This chamber is provided with a metal tap-hole E at the bottom and a slag taphole F near the top edge thereof. y ,An observation-port K will enable the operator to observev the condition of the receiving-chamber.
There are ay number of Hue-openings G lead' ing from the top of the receiving-chamber to a main flue G on either side of the receivingchamber and passing thence through the walls of the stack upon opposite sides of the smelting-chambervand communicate with the stack above the chamber, the purpose of which is to carry away the fumes and gases generated from the molten metal.
In the operation of my furnace I use liquid fuel, and the manner in which it is applied is shown in Fig. l. The oil being fed to the furnace through'the oil-pipes I and the combined steam and air being fed thereto through the pipes J, the said pipes leading into the pipe I J, in which the air, oil, and steam will be properly mingled and from which it will be fed to the receiving-chamber, where these substances will burn with intense heat in the upper center of the receiving-chamber above the molten metal and slag below the ore on the grate. I have shown this form of device vfor heating my furnace with liquid fuel; but
I do not confine myself to the method herein shown, as the same can be heated by other yappropriate means for burning liquid fuel and not depart from the spirit of my invention.
It will be manifest that a smelting-furnace embodying my invention may be continuously operated because of the fact that it has a smelting-chamber provided with a grate comprising a series of grate-bars so arranged that they will receive the ore to be smelted in the receiving-chamber, properly spaced apart so as to permit it to pass immediately itv comes to a molten statedown through the grate into the receiving and combustion chamber directly underneath the smelting-chamber, where the metal and the slag may be separated and removed and the metal tapped olf, the same being heated by a liquid fuel, which leaves no refuse to be removed.
IOO
Through the medium of such an apparatus it is my object and aim to smelt all kinds of ores by the use of liquid fuels, the furnace being fitted with the liquid-carbon heat-producing system, which produces intense heat by the combustion of oil and air and leaves no residuum which requires means for its removal. By this arrangement a saving of from forty to fifty per cent. may be obtained as compared with the old system of smelting ores by the use of coke as a fuel.
Any stack cupola-furnace can be fitted with my invention at a very small expense.
A new furnace can be built at small outlay as compared with the expense of constructing one of the old type with a capacity equaling mine.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
A smelting-furnace comprising a smelting and a receiving chamber adjacent to the bottom of the stack, a grate between said chambers composed of grate-bars of suitable material properly spaced apart, the lower ends of the grate-bars resting in footing in the side walls of the stack and projecting therefrom in an upwardly-inclined angle and abutting the opposite bars at the center of the stack, the receiving-chamber being substantially oval-shaped at the bottom as shown; an observation-port in the wall of the said receivingchamber; a slagremoving port; a metal-tapping port and ports for the passage therefrom of the metal fumes, the said ports opening into the top of said receiving-chamber and communicating with a flue extending therefrom to and into the stack above the smelting-chamber, in combination with means to apply liquid fuel thereto substantially as shown and described, Y
In witness that I claim the foregoing I have hereunto subscribed my name this 21st day of June, 1902.
